Angry center dash big wiring PROBLEM !!

I was going to change my center dash vent bulbs from white to led blue, so I removed the center vent piece (right below the sunglass holder compartment) and I was trying to remove the 10 wire plug-in to remove the vent piece from the car. Since I did not read any instructions BEFORE I started, I removed the top of the plug-in to see how it could be detached from the piece. When I removed the top of the plug-in all the wires fell out and now I do not know how the wires go back into their correct settings. see photo!!! Can anyone help me as to how the right wires go back into the correct holes. Maybe a photo (the best for me) or a wiring diagram. As you can see in the photo, I have tried to guess as to the length and how the wires line up to coincide with some slight wear on the plug itself and minimal corrosion marks on the plug holes as to where the wires may go but so far I have not had any luck.
HELP !!!!!!



Any suggestions ?
thanks
Steve

A complete set of R129 wiring diagrams is available as a small download: R129 ETM 64.

That's not possible. {...Checking...}

Dammit!

I've uploaded it again, and as a check, I downloaded and installed with no problems. Here is the link: R129 ETM 64. I had to override Windows Defender automatically blocking an .msi file. You may have to override the default security of Internet Explorer as well. There is some Java code running mixed with HTML. I created this package myself. I couldn't incorporate malware if I wanted to, since I haven't a clue how to do it.

It's module N18/2 in the my copy of the ETM about page 176, terminals and wire codes:

9 - wh/bk
12 wh/rd
11 ye/gy
5 (two wires in) bn/ye
10 bk/bn
8 bk/rd
6 bk/ye
3 bk/gn
7 (two wires) ye/gy
2 bn
1 gy/bu

terminal order left to right on depiction of module, I'm too lazy to do the cut-n-paste reordering
the terminal numbers are on the plug... you probably already know that the second color is the stripe.
